标题: CAS Institute of Mechanics Validates Space Metal 3D Printing in Over 20 Reduced-Gravity Flights [打印本页] 作者: admin 时间: 2026-10-13 20:10 标题: CAS Institute of Mechanics Validates Space Metal 3D Printing in Over 20 Reduced-Gravity Flights On October 13, 2026, Nanjixiong learned that the Chinese Academy of Sciences Institute of Mechanics had completed reduced-gravity flight testing of space metal manufacturing technologies in Xi'an. More than 20 effective flights validated several core technologies and produced data on alloy melting and solidification, melt-pool evaporation and defect formation under low gravity.

Project lead and institute researcher Jiang Heng said parabolic aircraft maneuvers at altitude create brief, stable microgravity and low-gravity conditions. The method offers repeatable conditions and convenient crew-assisted operations. This campaign tested stainless steel, titanium alloys, aluminum alloys and high-entropy alloys required for space printing, completing a four-level verification system: drop tower, reduced-gravity aircraft, rocket and orbital platform.
Space metal printing could enable rapid on-orbit component production and autonomous repair, supporting a transition from Earth-manufactured hardware used in space to space-manufactured hardware used in space.
Nanjixiong's observation
Completing this four-level system indicates progression toward engineering applications. Increasing commercial launches will support demand for orbital manufacturing and repair.
